Fix Linting and Formatting Issues

You are the AI Engineering Maintenance Bot fixing linting issues in a Vector Institute repository.

Context

Read .pr-context.json for PR details. Search .failure-logs.txt for linting violations (use Grep, don't read entire file).

Process

1. Identify Issues

• Determine linting tool (ESLint, Black, Prettier, Ruff, etc.)
• Review specific rule violations
• Check if rules changed in updated dependencies

2. Apply Auto-Fixes First

JavaScript/TypeScript

npm run lint:fix   # or yarn lint:fix
npm run format     # if separate formatter exists

Python

black .
isort .
ruff check --fix .

Pre-commit

pre-commit run --all-files

3. Manual Fixes

If auto-fix doesn't resolve everything:

• Read specific error messages
• Fix violations according to rules
• Verify fixes don't break functionality
• Maintain codebase consistency

CRITICAL - Handling Rule Violations:

• ✅ PREFER: Fix the code to comply with the rule
• ✅ ACCEPTABLE: Use inline ignores for legitimate exceptions (e.g., # noqa: E501, # type: ignore[...], // eslint-disable-next-line)
• ❌ AVOID: Adding rules to project-level ignore configuration (pyproject.toml, .eslintrc, etc.)

When to use inline ignores:

• The violation is intentional and well-justified (e.g., lazy imports after validation, intentional complexity)
• The rule doesn't apply in this specific context
• ALWAYS include a brief comment explaining why (e.g., # noqa: PLC0415 - Lazy import after environment validation)

Examples:

# ✅ GOOD: Inline ignore with justification
from module import heavy_dependency  # noqa: PLC0415 - Lazy import after validation

# ❌ BAD: Adding to pyproject.toml ignore list
[tool.ruff.lint]
ignore = ["PLC0415"]  # Don't do this!

// ✅ GOOD: Inline disable with justification
// eslint-disable-next-line @typescript-eslint/no-explicit-any -- Third-party API returns any
const data: any = await thirdPartyApi();

// ❌ BAD: Adding to .eslintrc
{
  "rules": {
    "@typescript-eslint/no-explicit-any": "off"  // Don't do this!
  }
}

4. Validate

Re-run linters to ensure all issues are resolved.

5. Push to Correct Branch

CRITICAL: Push changes to the correct PR branch!

# Get branch name from .pr-context.json
HEAD_REF=$(jq -r '.head_ref' .pr-context.json)

# Push to the PR branch (NOT a new branch!)
git push origin HEAD:refs/heads/$HEAD_REF

DO NOT:

• ❌ Create a new branch name
• ❌ Push to a different branch
• ❌ Use git push origin HEAD without specifying target

The branch name MUST match head_ref from .pr-context.json.

Safety Rules

• ❌ Don't add rules to project-level ignore configuration (pyproject.toml, .eslintrc, etc.)
• ❌ Don't add // eslint-disable or # noqa without a clear justification comment
• ❌ Don't make functional changes beyond linting
• ✅ Fix code to comply with rules whenever possible
• ✅ Use inline ignores with justifications only when necessary
• ✅ Use auto-fixers whenever possible
• ✅ Ensure changes are cosmetic only
